Amplify your building performance

Sefaira’s analysis is nimble enough to keep up with the pace of conceptual and schematic design. Run full annual simulations powered by industry-accredited analysis engines, and get your building performance results in minutes instead of weeks.

Pick the right strategies

Compare massings, layout, and envelope options to shortlist the right concepts. Study natural ventilation and HVAC systems for all project types.

Get consensus

Share your project using compelling visuals to convince others of your proposal’s merits and the performance benefits of your design.

Advance projects confidently

See how your project is tracking against energy, daylight, and comfort goals, using ASHRAE and other industry standards as your guide.

Concept and schematic design game-changer

Fast & easy to use

Model simple geometry in SketchUp, run analysis to get your first results within minutes, and share proposals using easy-to-understand graphics.

Credible

Run hour-by-hour annual simulations using industry-accredited EnergyPlus and Radiance. Dial-in your instance using a wide range of inputs & controls.

Collaborative

Easily peer-review results, work as a team, and across firms, on shared projects by leveraging Sefaira’s cloud-based platform.

Sefaira
Make smart design decisions

The metrics you need

Energy use and carbon emissions

Understand your design’s impact on energy cost and CO2 emissions while also measuring the potential impact of a renewable system.

Thermal comfort

See how shading improves operative temperatures and measure the impact of window openings on air temperature.

Daylight

Choose between Daylight Factor, Direct Sun Exposure, and Annual Daylight outputs (including Spatial Daylight Autonomy sDA).

HVAC

Quickly assess the impact of your architectural features on HVAC sizes and generate preliminary sizes to improve cost estimation.
